We had the start of functions that operated on little endian bitmaps.
This adds more operations and uses __packed to support unaligned bitmaps
on platforms where unaligned accesses are a problem.

The swizzle value was defined in terms of longs but the code used u64s.
And the bare shifted value was an int so it'd get truncated. Switch it
all to using longs.
The ratio of bugs to lines of code in that first attempt was through the
roof!

We're going to need to start setting bloom filters bits in mkfs so we'll
add this trivial inline. It might grow later.
